Description
A WASTEWATER VALVE ARRANGEMENT
TECHNICAL FIELD
The present invention relates to a wastewater valve arrangement.
BACKGROUND
The reference to any prior art in this specification is not, and should not be taken as an acknowledgement or any form of suggestion that the prior art forms part of the common general knowledge.
Wastewater systems, including sewage systems, are inherently affected by the presence of unwanted pressurized air in pipelines that can result in operational problems such as broken pumps, valves and pipes. In order to minimise these problems, air release valves (ARVs) are located at the highpoints of pressurised pipelines to de-aerate the pipelines and relieve any excess pressure.
An ARV typically includes a receptacle engaged with the pipeline to receive pressurized air and wastewater. A float valve is fitted to the receptacle and releases air in the receptacle as pipeline pressure increases. The float valve also permits the ingress of air into the receptacle as pipeline pressure decreases. The float valve further includes a float which rises with the wastewater level in the receptacle, to close the valve and thereby prevent wastewater from exiting the ARV.
In practice, wastewater flotsam builds up within the receptacle over time and can have a detrimental effect on the operation of the ARV. Accordingly, it is often necessary to periodically clean the interior of the receptacle from flotsam which can be an arduous task. Furthermore, wastewater flotsam can clog up the float valve and thereby render the ARV ineffectual.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
According to an embodiment of the present invention, there is provided a wastewater air release valve ARV 2 shown in Figure 1 which is suitable for fitting to the pipeline 4 of a sewage system. The ARV 2 includes a filtration receptacle 6 for receiving a removable filter 8 to filter wastewater. A valve receptacle 10 is provided for receiving the filtered wastewater from the filtration receptacle 6. The ARV 2 further includes a float valve 12 which is fitted to the valve receptacle 10.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
According to an embodiment of the present invention, there is provided a wastewater air release valve ARV 2 shown in Figure 1 which is suitable for fitting to the pipeline 4 of a sewage system. The ARV 2 includes a filtration receptacle 6 for receiving a removable filter 8 to filter wastewater. A valve receptacle 10 is provided for receiving the filtered wastewater from the filtration receptacle 6. The ARV 2 further includes a float valve 12 which is fitted to the valve receptacle 10. The float valve 12 permits the release and ingress of air relative to the valve receptacle 10, and impedes the egress of filtered wastewater from the valve receptacle 10. A detailed description of the ARV 2 is provided in detail below.
The filtration receptacle 6 includes a container 14 to which a lid 16 can be fitted in air tight engagement using an 0-ring (not shown). The lid 16 is releasably fastened to the container 14 using fasteners 18 that take the form of nut and bolt arrangements. A handle 20 is mounted to the lid 16 to facilitate hand separation of the lid 16 from the container 14. The base of the container 14 defines a throat from which a flange extends. The flange can be mounted to the pipeline 4 using fasteners 22 so that the throat of the container 14 is in register with an aperture 24 defined in the pipeline 4.
The ARV 2 further includes the filter 8 which, in turn, includes an endless mesh wall 26. The filter 8 further includes a solid inlet tube 28 which extends from the base of the mesh wall 26. The base of the mesh wall 26 also defines a throat so that the inlet tube 28 has a lesser cross sectional area than the upper end of the mesh wall 26. The filter 8 further includes a handle 30 mounted to the top of the mesh wall 26 to facilitate hand removal of the filter 8 from the container 14.
5 A pair of open connection tubes 32a,b interconnect the receptacles 6,10 so that fluid can freely pass between them. These two spaced tubes 32 provide for a structurally stable ARV 2.
The valve receptacle 10 includes a container 34 to which a lid 36 can be fitted in air tight engagement using an O-ring (not shown). The lid 36 is releasably fastened to the container 34 using fasteners 37 that take the form of complementary nut and bolt arrangements. The lid 36 defines a central aperture through which the float valve 12 extends when fitted.
The float valve 12 includes a float 38 at its base that defines an underside recess. In use, wastewater filling the container 34 lifts the float 38 and thereby traps air in the underside recess. The float is not prone to implosion as there is no significant pressure differential between the air in the underside recess and the air in the container 34.
The float valve 12 further includes a bent housing 40 in which an annular seat 42 is fitted. An arm, extending from the float 38, terminates in an upper stopper that engages with the seat to close the valve 12. The float valve 12 is configured to be normally open and closes as the wastewater level rises in the valve receptacle 10.
In use when the pipeline pressure increases, wastewater (i.e. sewage) including flotsam and other debris exits the pipeline 4 and enters the filtration receptacle 6. In turn air in the filtration receptacle 6 passes through the connection tubes 32a,b, the valve receptacle 10 and out through the float valve 12. As the wastewater level in the filtration receptacle 6 increases, wastewater passes into the valve receptacle 10 via the filter 8 and connection
The valve receptacle 10 includes a container 34 to which a lid 36 can be fitted in air tight engagement using an O-ring (not shown). The lid 36 is releasably fastened to the container 34 using fasteners 37 that take the form of complementary nut and bolt arrangements. The lid 36 defines a central aperture through which the float valve 12 extends when fitted.
The float valve 12 includes a float 38 at its base that defines an underside recess. In use, wastewater filling the container 34 lifts the float 38 and thereby traps air in the underside recess. The float is not prone to implosion as there is no significant pressure differential between the air in the underside recess and the air in the container 34.
The float valve 12 further includes a bent housing 40 in which an annular seat 42 is fitted. An arm, extending from the float 38, terminates in an upper stopper that engages with the seat to close the valve 12. The float valve 12 is configured to be normally open and closes as the wastewater level rises in the valve receptacle 10.
In use when the pipeline pressure increases, wastewater (i.e. sewage) including flotsam and other debris exits the pipeline 4 and enters the filtration receptacle 6. In turn air in the filtration receptacle 6 passes through the connection tubes 32a,b, the valve receptacle 10 and out through the float valve 12. As the wastewater level in the filtration receptacle 6 increases, wastewater passes into the valve receptacle 10 via the filter 8 and connection
6 tubes 32a,b respectively. Accordingly, flotsam is impeded from entering the valve receptacle 10 and remains within-the filter 8.
Compressed air is trapped at the top the filtration receptacle 6 as the wastewater level rises therein above the connection tube 32a. This compressed air cannot escape as the lid 16 is fitted in air tight engagement with the container 14, and facilitates flushing of flotsam back into the pipeline 4 when the wastewater level (and pipeline pressure) drops. The wastewater fills the ARV 2 at a controlled rate and thereby prevents a shock or water hammer condition from occurring that might otherwise damage the ARV 2 or pipeline 4.
As the filtered wastewater level increases above a predetermined threshold within the valve receptacle 10, the valve 12 closes as previously described to thereby impede the egress of wastewater from the valve 12. As the pipeline pressure drops with decreasing wastewater level, the valve 12 opens once more to permit the ingress of fresh air into the ARV 2.
Periodically, the user can clean the ARV 2 of collected wastewater flotsam.
The lid 16 is unfastened from the container 14 and removed using the lid handle 20. In turn, the user can readily remove the filter 8 from within the container 14 using the filter handle 30. In practice, the filter 8 holds accumulated flotsam which is prevented from reaching and otherwise clogging the valve 12. Much of the heavier filtered flotsam rests in or upon the base tube 28 and can be extricated using a pipe cleaner. The mesh wall 26 of the filter 8 can be subsequently cleaned using a high pressure hose, and the filter 8 can then be returned to the cleaned container 14. The high pressure hose can also be used to clean the interior of the container 34 and float valve 12 upon removal of the lid 36.
A person skilled in the art will appreciate that many embodiments and variations can be made without departing from the ambit of the present invention.

In another embodiment shown in Figure 2, the connection tubes 32a, 32b divergently extend from the filtration receptacle 6. Once again, compressed air is trapped at the top the filtration receptacle 6 as the wastewater level 100 rises therein above the mouth of connection tube 32a. Compression of the air within receptacle 6 in the embodiment of Figure 2 occurs sooner than the embodiment of Figure 1.
